, 2007 准噶尔无叶豆种子具有明显的地理种群大小变异的现象。对大、小种子在3种光照(持续光照,12/12小时光照/黑暗,全黑暗)、5个温度梯度(10℃,15℃,20℃,25℃,30℃)条件下的最适萌发条件进行研究,结果表明:大、小种子萌发的适宜光照条件均为12/12小时光照/黑暗,在持续黑暗与持续光照条件下的萌发率无显著差异;最适温度范围是20~25℃,大种子在20℃、25℃下的萌发率(>85%),萌发指数均显著高于相同温度条件下小种子的萌发率(

, 2000 在岷江上游大沟流域 ,沿着人为干扰梯度 ,调查了退化榛栎群落的结构及其物种组成变化。结果表明 :(1)除密度外 ,群落木本层的结构特性 (密度、高度、生物量、基径面积和物种多样性 )与干扰强度的增加呈负相关 ,而其草本物种多样性、生态优势度呈正反应 ,但地上生物量变化呈现相反的趋势 ;(2 )根据群落内植物种群密度 (或盖度 )在干扰梯度上的响应变化 ,群落内 4 7个种可基本上分成 3个反应种组 :16个为扩展种 (invasivespecies) ,随干扰强度增大而种群数量明显增多。 6个为敏感种
